The Gas Transmission Rate Tester (GTR Tester) measures gas transmission rate (gas barrier property) of packaging materials such as plastic films.
Measurement of gas transmission rate of polymer films such as plastic films, etc. is important because, for example in case of packaging materials, preservation of the content of a package considerably depends on the gas barrier property of the packing material.
Recently gas transmission rate measurement is being used in new fields such as functional polymer films.
Features
– An automatic valve is used to realize fully automatic measurement. (No need for conventional manual valve operation)
– Many kinds of gases can be measured. (Differential pressure method)
– Additional expansion is possible by modular design.
– Since measurement is performed while data is stored, data can be analyzed even during testing.
– Mail transmission function allows you to receive a message when an error occurs or the test ends.
– Allows analysis of diffusion coefficient and solubility coefficient (Optional)
– High sensitivity vacuum pressure gauge of reading accuracy 0.25% is employed.
– Specimen table supports two different sizes of specimen.
– Performs temperature error correction of transmission gas.
